Question

a lens is a curved transparent material that refracts light. concave lenses curve inward or bend light in a process known as refraction. light enters the lens, a medium, in a straight line. the lens slows the light down and refracts it. because the lens is thinner in the middle than it is on the edges, the light diverges or spreads out, as shown in the lens. which statement is true about light? it curves around corners. it travels in a straight line. it travels in circles.

Explanation:

Light travels in a straight line in a homogeneous medium. This is a fundamental property of light. When light enters a lens (a medium), it slows down and bends (refracts), but the initial path of light (before entering the lens) is straight. The statement "It travels in a straight line" aligns with this property. The other options are incorrect. Light does not curve around corners (diffraction is a minimal effect for visible light around large - scale corners in daily life compared to straight - line propagation) and it does not travel in circles.

Answer:

It travels in a straight line.
